106-106: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAdd a case for the
unknownpatch status.The new tests cover
cleanandconflict. They do not cover the fail-closedunknownpath, which_patch_apply_statusreturns when the checkout is not the PR head or when a fetch fails. That path is the one that keeps a wrong DB out of Tier 2, and_selection_accepts_pr_diffmust also decline for it. A regression that returnedcleanon a failed fetch would pass the current suite.Add a small test that calls
_patch_apply_statuswith apr_headvalue that does not matchHEADand asserts"unknown".💚 Proposed additional test

In `@jenkins/scripts/cbts/coverage_selection/artifact.py`:
- Around line 218-226: Update _run_git to pass the module’s existing bounded
timeout to subprocess.run, and handle timeout expiry in _patch_apply_status by
returning unknown so stalled git fetch operations decline Tier 2 rather than
blocking CI.
In `@tests/unittest/scripts/test_cbts_coverage_artifact.py`:
- Around line 109-133: Replace the Git switch commands in the fixture setup
around the clean_db and conflicting_db branches with Git-compatible checkout
commands, using checkout -b when creating branches and checkout when returning
to pr. Preserve the existing branch names and commit flow without adding a
capability gate.
